Question:
Male, 18 years old, Deletion subtype
My son has low testosterone and is seeing an endocrinologist tomorrow to possibly start increasing this hormone. Is there anything I should look out for? He is at a good weight but has low energy. The primary doctor believes it could be because of the low testosterone. Any thoughts on this would be greatly appreciated.
Nurse Lynn’s Response:
Low testosterone is very common in males with PWS and can cause problems like low energy, tiredness, weak muscles, low bone strength, and sometimes mood changes. Doctors often recommend testosterone treatment, especially for young men who are otherwise at a healthy weight but still feel very tired. Research shows that testosterone may help people with PWS build muscle, lose fat, strengthen their bones, and sometimes improve mood and energy. These benefits are important because people with PWS often have weak muscles and weaker bones as they get older.
There are also some things to watch out for with testosterone treatment. In some people with PWS, it can cause mood swings, irritability, or frustration, though studies show this doesn’t happen often and is usually mild. If he uses skin patches or gels, he may get irritation at the site, and if he picks at his skin, this can be a bigger problem. Injections are another option. Doctors will also want to check his cholesterol, liver, and bone health.
At the endocrinology visit, it’s good to ask what his testosterone levels are now, what kind of treatment the doctor plans to use, and what the main goals are, whether that’s more energy, stronger muscles, healthier bones, or a mix of all three. It’s also important to ask how often he will have checkups and blood work to make sure the treatment is safe. If his low energy is from low testosterone, treatment can really help, but it works best when started slowly and with careful follow-up. Combined with good food choices, exercise, and healthy sleep, testosterone may improve both his health and his quality of life.
